SLIDING WINDOW-BLIND.

Specification of Letters Patent.

Application filed December 31, 1910.

Serial No. 600,232.

invented new and useful Improvements in Sliding \Vindow-Blinds, of whichthe following is a specification.

This invention relates to sliding window blinds, and has for an objectto provide an improved form of hanger which may be conveniently arrangedon the house structure in suitable proximity with the window and whichis constructed to slidably support the blind so as to permit of itsconvenient adjustment.

Another object of the invention is to provide an improved form oflocking means operating to hold the blind in its adjusted positions.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:Figure 1 is a front view of the blinds and the hanger therefor showingthe application of the same to a window structure, the blinds being intheir open positions. Fig. 2 is a horizontal section on line 2-2 ofFig. 1. Fig. 3 is a vertical section on line 33 of Fig. 1. Fig. 4 is avertical section on line 44 of Fig. 1. Fig. 5 is a fragmentary viewshowing portions of the blinds and illustrating them in their closedpositions.

The structure herein contemplated embodies a hanger including parallelupper and lower bars 1 and 2, each of which has its end portionsapertured, as at 3, for a purpose to be presently described. Supportingcollars or brackets 3 are fitted to the apertured ends of the said rod,and as shown, clamping bolts 4 extend through the collars and throughthe apertures in the ends of the rod. The collars or brackets areprovided with attaching means for engagement with the wall of thebuilding, as shown. At the center, each rod is supported by a bracketmember 5 which is also secured to the wall of the building, as shown.

It will of course be understood that any suitable number of blinds maybe supported by hangers, but as illustrated, two of such blinds, asshown at 6, are supported by the rods, and as shown, each blind is provided at its upper end with suitably spaced eye members 7 receiving theupper rod and at the lower ends the blinds are provided with eye members8 receiving the lower rod.

The lower rod 2 is provided with an inwardly extending web 9 which isprovided with a longitudinal series of passages 10 for a purpose to behereinafter described. The lower guide eye members 8 are formed withportions 11 receiving the said web portion of the rod 2, as clearlyshown in Fig. 3 of the drawing. The blind 6 at the left is provided witha bracket 12 having horizontally disposed superimposed ears 13 in whichthe sliding locking pin 14 is re-v movably mounted. The blind 6 at theright is provided with a bracket member 15 having superimposed spacedears 16 which fit between the ears 13 when both blinds are in theirclosed positions. The ears 16 are provided with openings 17 toaline withthe openings in the ears 13 when the blinds are closed and when theblinds are open the apertures in the ears 16 receive a sliding lockingpin 18 which is identical in construction with the pin 14. The pin 18may be removed when the blinds are in their closed positions and the pin14 may be extended through the ears 13 and 16 respectively, and into oneof the passages 10 in the web portion 9 of the rod 2. The blinds arethen locked. The blinds may be opened by sliding them away from eachother and they may be held against sliding movement through theinterchangeable locking engagement of the pins 14 and 18 respectively,in the opening 10 in the bar 2.

I claim 1. In a sliding blind structure, upper and lower tracks, a pairof blinds slidably adjustable on the tracks, the lower track having alongitudinal series of perforations therein, apertured members carriedby the blinds, a fastening device carried by each blind and adapted tobe extended through the apertured member of the blind andinterchangeably engaged in the perforations in the lower track, the saidapertured members of the blinds being adapted for interfittingengagement when the blinds are closed and having their aperturesarranged in coincidence when the blinds are closed and arranged toreceive the fastening device of one of the blinds so as to hold theblinds closed against each other.

2. In a blind structure, superimposedtracks, blinds slidably supportedby the tracks, the lower track having an inwardly Patented July 4, 1911.

extending web portion, the said Web portion having a longitudinal seriesof perfo rations therein, apertured members interfitting each other whenthe blinds are closed, and fastening devices extending through theapertured members and interchangeably engaged in the perforations in theweb so as to hold the blinds against movement, one of the said fasteningdevices being adapted to be extended through the said apert-ured membersof the blinds when the blinds are closed and to be engaged in one of theperforations in the web so as to hold the blinds against slidingmovement and to hold them closed against each other.

In testimony whereof I aflix my signature in presence of two witnesses.
